BQN kicks-ass and I've spent hours listening to the Array Cast podcast while in SoCal traffic. I'll check his stuff out with an eye towards the audio stuff.

I'm an APL newb... while I've been writing code-for-cash forever (C, etc.) I've had a long-time interest in APL languages, but I'm just messing around after working on waveform generation for another sound project I have in the works (https://github.com/octetta/skred ... https://youtu.be/L5-3gBpJsAo?si=JdBlntzn4doY-c3s).

While I was working on this I remember the first book I saw in the public library on computer programming was about APL (probably sometime around 1976)... I didn't have access to a "real computer" for another year after that and no APL for decades, but some ideas stick around, LOL.
